Abstract (en)

The present invention provides a non-aqueous electrolyte solution comprising a non-aqueous solvent and a lithium electrolyte, and a lithium secondary battery using the same wherein the non-aqueous solvent is obtained by adding a phosphoric acid compound prepared by substituting at least one hydrogen atom in phosphoric acid or polyphosphoric acid with a group represented by the general formula Ä1Ü: <CHEM> wherein, X represents Si, Ge or Sn atom, and each of R<1> to R<3> independently represents an alkyl group having 1 to 10 carbon atoms, an alkenyl group having 2 to 10 carbon atoms or an aryl group having 6 to 10 carbon atoms. <IMAGE>
